Anti-MRM3 antibodies are used in the immunodetection of the protein mitochondrial rRNA methyltransferase 3. In humans, the canonical protein has a reported length of 420 amino acid residues and a mass of 47 kDa. Its subcellular localization is in the mitochondria. It is noted to be expressed at same level in normal liver and hepatocarcinoma. It is a member of the RNA methyltransferase TrmH protein family. Synonyms for this target antigen include RNMTL1, rRNA methyltransferase 3, mitochondrial, 16S rRNA (guanosine(1370)-2'-O)-methyltransferase, 16S rRNA [Gm1370] 2'-O-methyltransferase, and RMTL1. MRM3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some MRM3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
